EUGENE W. GAMPAG-NA, OF RANDOLPH, MASSACHUSETTS.

POCKET SAW-JOINTER.

Specification of Letters Patent.

Application filed. May 15, 1908.

Patented Aug. 24, 1909. Serial No. 433,022.

To all whom it may concern:

Be it known that I, EUGENE W. CAM- PAGNA, a citizen of the UnitedStates, residing at Randolph, county of Norfolk, and State ofMassachusetts, have invented an Improvement in Pocket Saw-Jointers, ofwhich the following description, in connection with the accompanyingdrawing, is a specification, like figures on the drawing representinglike parts.

This invention relates to saw jointers adapted to level and even up theteeth of saws after they have become worn, and the invention has for itsparticular object to provide a novel device for holding the file bywhich the jointing operation is accomplished, all as will be more fullyhereinafter described and then pointed out in the claim.

The drawings sli'ow a saw jointer embodying my invention and the mannerin which it is used.

Figure 1 is a perspective view of a portion of a saw showing the mannerin which my improved saw jointer is used Fig. 2 is a side view of thefile-holder; Fig. 3 is substantially a section on the line x-:c, Fig. 1Fig. 4 shows the manner in which the device may be used as a gage.

My improved jointer is formed of a single piece of sheet metal which isbent into the desired shape. The completed jointer or file-holder isformed with the two arms or side pieces 3 which form between them aspace to receive the saw 4 and each of which is bent outwardly at 5 toform the file-receiving opening or ocket 6. Immediately above thefile-receivlng pocket 6 the two sides of the jointer are bent into closeproximity with each other and then are shaped to form the roundedportion 8 which constitutes a pencil-receiving recess.

The device is made of resilient material. In using it as a saw jointer,a file 10, preferably a three-cornered file, is inserted into thefile-receiving pocket 6, as shown in Figs. 1 and 3, the two faces of thefile resting against the fiat sides of the pocket and the ,third face ofthe file standing square across the jointer in position to act on theends of the saw teeth. After the file has thus been inserted into theholder, it is placed over the saw, the two side pieces 3 embracing thesides of the saw and acting to guide the j ointer in its movement overthe saw.

In using the device, the operator grasps the two sides with the thumband fore finger, as shown in dotted lines Fig. 1, and allows the palm ofthe hand to rest on the top of the file. In this way the file may beheld in its proper position and yet sufficient pressure may be a pliedthereto to properly accomplish the esired object.

Owing to the fact that the device is made of resilient material, thesides thereof will be resilient at the point 7 above the file-receivingpocket and again at the point immediately below the file-receivingpocket, so that files of different sizes may be readily used. If alarger file than that shown in the drawings is used, the resiliency ofthe sides permits the portions 3 to be closed onto the sidgs of the saw,so as to properly guide the too My improved device is also ca able ofuse as a gage, as shown in Fig. 4. hen used in this way, the file isremoved and a pencil 20 is inserted into the encil-receiving recess 11,and the sides of t 1e device may then be grasped by the operator withhis thumb and fore finger and pinched together, thus causing the pencilto be gripped firmly. The edge of the holder may then be brought againstthe corner or edge of a block or board 12 on which a mark 13 is to-bemade parallel to the edge and by passing the device along the edge ofthe block in a manner similar to that in which a gage is operated, thedesired line 13 will be made.

If desired the edges of the device may be notched where thefile-receiving pocket 6 terminates, and this notch makes a convenientguide to engage the edge of the board.

My improved device is comparatively fiat and thin and is constructedwithout sharp corners so that it can be readily carried in a personspocket without inconvenience and without injuring the clothing.

Having fully described my invention, what I claim as new and desire tosecure by Let- V ters Patent is A saw jointer made from a single pieceof resilient sheet metal doubled on itself to present two sides adaptedto embrace a saw} name to this specification, in the presence of andelse to dreslint a pincil-receivinglportion Q two subscribing Witnesses.11, eaci s1 e eing ent outward y at 5 thereby to form a file-receivingpocket said EUGENE CAMPAGNA' 5 sides being resilient at points bothabove and Witnesses:
